' Patented oet. 22, 1912.

Application led May 17, 1912. 'Serial No. 697,889.

To all whom it may concern: y

Be it known that I, JOSEPH THEISEN, a citizen of the United States of America, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Vacuum-Cleaners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it ap- .pertains to make and use the same. f

My invention relates to improvements in vacuum cleaners and its object is to provide a portable device of this class which will effectively remove the dust and other impurities from carpets, articles of furniture and various other objects and deposit the same within a receptacle provided therefor so that the exhaust air from said receptacle will be entirely free from the same and to provide the device with various other new and useful features of construction and arrangement as hereinafter more fully described and particularly pointed out in the claims.

This device consists essentially of a rotary blower which produces a current ofy air driven by any convenient motor located adjacent thereto, both blower and motor being mounted upon the cover of a receptacle partially filled with water. The current of air carrying dust and other impurities is deflected against the surface of the water by inclined plates within the receptacle and as this current of air strikes the water it will.

deposit the dust and other impurities in the water which will settle to the bottom of the receptacle and the purified air will be exhausted through an opening provided for that purpose in the coverof the receptacle. Removable plugs are provided for removing the contents and refilling the receptacle and various other details of construction are em. bodied in this invention as will more fully appear by reference to the accompanying drawings, in which:

Figure 1 is a sectional elevation through the axis of the blower; Fig. '2 is a detail in transverse sectional elevation with the cover of the blower removed; Fig. 3 is an inverted view showing a section on the line 3 3 of Fig. l; and Fig. t'is a detail in sectional ele'- vation of one corner of the machine showing the exhaust outlet.

Like numbers refer to like parts in all of the figures.

1 represents the base of the machine which is hollow and forms a receptacle which when 1n use is partially filled withA water, removable plugs Q'being provided at opposite ends of the case for the purpose of filling or emptying the same.

A rotary blower 8 preferably of the centrifugal type is mounted on the case and driven through a shaft ll by any convenient form of motor'lO preferably mounted on the case adjacent to the blower. The blower has an inlet opening provided with a nipple 9 which is a/daptcd to'receive one end of a flexible tube, the other end of the tube `being provided with the ordinary suction dust collector (not shown).

The rotation of the blower will draw-in a current of air carrying therewith dust and other impurities, and force the same into the casing 1 through the inlet passage 3. As this mlixture enters the case it circulates through the passage at one side of a partition 6 extending from top to bottom of the case. against the surface of the water contained within the case 'by inclined plates 5 which extendl from across the passage the lower edges of said plates being slightly spaced away from the surface of the water and the upper edges attached to the cover. As the air engages the surface of the water the dust and other impurities carried thereby will be depositedin the water and settle to the bottom thereof and the purified air will passv out of the casing through the exhaust pasv sage 4 locatednear one corner ofthe cover ,of the same.

A complete circulation of air in the case is lprevented by a partition 7 which extends from one side of the case to the partition 6 at the side opposite the deflecting plates 5.

The mixture is deflected downward- This partition 7 projects downward beneath the surface of the water but does not extend to the bottom of the case leaving a Apassage below the partition to 'permit the water to circulate therethrough. rIhis arrangement will eiectively stop the circulation of air but will-allow a slow circulation of the water due to the impulse of the air against its surface. This circulation of the water is advantageous in that it insures an equal deposit of sediment over the entire bottom of the receptacle.

This device is portable and the receptacle may be cleaned and refilled by removing both caps 2 and allowing the stream of water to enter one opening and iow through opening and thus removing vthe deposit Itherein Y, l

' What I claim is l. A vacuum cleaner, comprising a receptacle adapted to be partially filled With Water, inlet land exhaust openings in said re-v ceptacle located at approximately opposite ends of'thesame, means for forcing a current of air into the .inlet opening,` a longitudinal partition in the receptacleto guide the current of air, a transverse partition to prevent a circuitous circulation of the same, and deiector plates in the current to direct the air agalnst the surface of the Water.

2. A vacuum cleaner, comprising a receptacle adapted to be partially lled with Water, inlet and exhaust openings located approximately .at opposite ends'of said receptacle, means for forcing air into the inlet opening, partitions in the receptacle adapted to guide the current of air and prevent a circuitous circulation ofthe same, said partitions being arranged to allow the Water Wit-hin the receptacle to circulate, delector plates in the path of the air current to deect the air against the surface of the Water. 3. Avacuum cleaner, comprising a receptacle adapted to be partially filled with Water, inlet and exhaust openings at approximately opposite ends of said receptacle, means for forcing air into the inlet opening, a longitudinal partition enga ing both top and bottom of the receptac e and being spaced apart from its ends, a transverse partltion extending between the longitudinal partition and one side of the receptacle engaging the top of the receptacle and projecting beneath the surface of the Water, and inclined defiector plates in the path of the air current to direct the air against the surface of the Water. i

i /I i the receptacle passing out of the opposite' Y. y

tacle adapted to be partially lled with water, inlet and exhaust openings in said ren path of the air.

4. A vacuum cleaner, comprising a recepceptacle, meansd for forcingfa current of air into the inlet opening mounted on the top of `said receptacle, a longitudinal partition in the receptacle engaging both the top. and bottom of'the same and spaced apart from its ends, a transverse partition extending between the longitudinal partition and one side .of the receptacle engaging the top of the receptacle and spaced apart from. the bottom of thev receptacle, and inclined de- Hector plates on the opposite side of the longitudinal partition and in the path of the air current to direct the air against the surface of the Water.

5. A vacuum cleaner, comprising a receptacle adapted to be partially filled With Water, inlet and exhaust openings at approxi- /mately opposite i ends of the receptacle, means for forcing a current of au' into the inlet opening mounted on the top of the receptacle, a longitudinal partition in the receptacle engaging both the top and bottoml of the saine and spaced apart from its ends, a transverse partition extending between the longitudinal partition and one side of the case engaging the top of the case and projecting beneath the surface of the Water, being spaced apart from the bottom of the case, and inclined detlector plates on the opposite sideof the longitudinal partition and in the path of the air current to direct the air against the surface of the Water and removable caps at opposite ends of the receptacle.

In testimony whereof I ailix my-signature in presence of tWo Witnesses.
